Overview
- Swiss digital asset bank Sygnum and lending startup Debifi announced MultiSYG on Oct. 24, 2025, with a public launch planned for the first half of 2026.
- Collateral sits in a five-party wallet shared by Sygnum, the borrower and independent signers, with any movement requiring a 3-of-5 approval.
- The non-custodial model is intended to keep funds verifiable on-chain and reduce single-point-of-failure risks highlighted by failures like BlockFi and Celsius.
- MultiSYG targets institutional and high-net-worth borrowers seeking bank-grade terms without surrendering full control of their bitcoin.
- The companies say the service will be available to Sygnum clients at debut.
